In addition to my previous article about GitLab service desk feature with iRedMail I would like to enhance it a little bit my fixing some missing parts. Starting with connecting to PostgreSQL vmail database: Verifying mail server connectivity and TLS issues. GitLab (and iRedMail also) does not allow expired certificates. So be sure to have both root CA present and your certificate valid. And finally restarting services. Interesting part is that only Nginx do not allow placing R11 root CA before actual certificate. But placing R11 after actual certificate does the job.
Failing Proxmox node and unable to access /etc/pve means that you have broken pmxcf. Analyse which services are stuck: Restart services: And in case it was stuck at updating certs (on which it got stuck in my case): In case UI is still unavailable: In my case, at this point it was fine.
I got 2.5GbE PCI-e card, but no drivers present in pfSense installation. To list devices: There is this Realtek network card: But there is no driver enabled: I installed realtek-re-kmod-198.00_3 package. It was few months ago, but I am pretty sure that is was from pkg and not by downloading it from some repository manually. Finally add to /boot/loader.conf: So you can either download from FreeBSD repository or:
Last time (somewhere around 2023) there was an option on Scaleway to install Proxmox 7 directly from appliance. There was also possiblity to use Debian 11 and install Proxmox atop of it. This time (2024/Nov) there is no direct install and installing on Debian gives me some unexpected errors which I do not want to overcome as it should work just like that. But there is option to use Dell’s iDRAC interface for remote access.
Instead of using dedicated Hetzner servers you can use their cloud solutions for less demanding use case scenarios. The idea is to have one server for pfSense and the other one for regular private use, hidden behind gateway. It will be little bit cheaper than renting dedicated server as CX22 costs around 3 – 4 Euro per month comparing to 50 Euro at least for dedicated server. You can have up to 10 virtual cloud server in a price of single dedicated server. Choose cloud for “simple” (or rather straightforward) solutions, dedicated servers for much complicated setups with much more
So we decided to try Zigbee wall switches and many of available brands work with Fibaro. But not all of them and not in all configurations. Even if some switch or module works it may only work with Tuya gateway and application and not with Fibaro gateway. So there are some blanks in this concept. We left with double frame with electronic switch and one blank for shutters as there is no compatible switch or module at this time. So I thought: maybe I just 3D-print it… OpenSCAD code: Few test desigs: Let’s print them: And here we go! Now
I use NextCloud as alternative to Google Photos. My smartphone sends pictures over OpenVPN to my NextCloud instance. However for over a year Android application has been showing notification that server version is outdated, and from time to time automatic upload do not work. So I decided that it is the time to do an upgrade. It did not work well: I tried to run upgrade using UI. It got stuck in various places, and finally I got this: But there is much simpler option. Install fresh copy of NextCloud. I prefer using VM ISO (https://www.turnkeylinux.org/nextcloud) instead of LXC containers.
At Indatify we use PostgreSQL for most of the time when dealing with data. We tried to use Cassandra, but for now it is too much of a constraint in such dynamic data environment. We put it on shelf. However, for textual data we choose Elasticsearch, because we know it and it provides full text search out of the box. Later, we will come back to Cassandra, but with more specified use case, as it requires precise data model to be predefined by query and not by structure. So, to install Elasticsearch (if running without sudo, then run from root):
In our lab we have 2 x HP z800 workstations. It is somehow ridiculous piece of hardware in terms of today standards. It’s got over 1 kW power supply, dual CPU motherboard and 12 memory slots. It is loud, draws loads of power and it’s got comparable gen 1 Intel CPUs as well as DDR3 – slow – memory. However it costs close to nothing and it is suitable for most small and mid applications. Official documentation says that the maximum memory capacity is 192GB of DDR3, which is 12 x 16 GB sticks working at 800 MHz. If we
